Opera 12 and Facebook

Hail!
I use Opera 12.16 and I suffer a drawback when I am into Facebook.
When I reach the end of a page, Facebook rearranges the whole page, there is much movement among the messages, and when the arrangement is finished I find myself almost at the top of the page or anyhow far from the message I was reading. I am peeved because of such behaviour.
Is it a drawback of Facebook or of Opera 12.16? Is there a setting of Opera 12.16 that can avoid it?

opera works great for me on facebook unless I'm playing a game, I usually open a window in Chrome or firefox for gameplay, opera just gives me endless security warnings. I can't find a security setting that will let me make exemptions for them. so I just play games on a different browser, no big deal I usually have several windows open anyway. I've been waiting for an update to fix it, but it has been 9 months or so, I tried reinstalling Opera but it doesn't seem to matter. If it is any consequence facebook games crash any browser after a while, they are just an evil habit I can't seem to break.... blessings

The security warning is by design in Opera's Presto-versions when visiting an SSL site that sends data out to a non-SSL web address, and thus won't be "updated to fix". Various websites persist in this insecure behavior, and various web browsers employ differing methods of dealing with it (or ignore it altogether). When SSL protocols are used to guarantee encrypted communications of personal data to a financial website, such a website forwarding of any user data "in the clear" to a non-SSL site constitutes a breach of security. Likewise, SSL can be used by non-financial sites to protect the privacy of non-financial personal data.

The problem arises when a website employs SSL to protect certain user-data like log-ins but is sloppily-coded to send certain other user data (like game keystrokes) out to non-SSL websites in the clear. A browser ought to trap such a breach in security to protect the user from this abuse of the SSL protocol, and Presto Opera versions do. Other browsers have elected various forms of over-ride (or total ignorance) of this security precaution. This is discussed at length in Annoying "Security Warning" Message.

Since the browser behavior is both the result of a conscious security decision on Opera's part for very good reasons and because Presto Opera will no longer be updated for features/improvements/bug-fixes, the behavior will not be changed.
